Solvent Dependent Spin-State Behaviour via Hydrogen Bonding in Neutral FeII Diimine Complexes 
Kelsey A. Schulte, Stephanie R. Fiedler and Matthew P. Shores

To use spin-crossover as a reporter for chemical sensing, it is important to understand how the local environment influences the complex’s spin state. The FeII pyridyl–imidazoline complexes described here allow us to separately assess the effects of external hydrogen bond donors, acceptors, and the intrinsic ligand fields.

The Influence of Water and Metal Salt on the Transport and Structural Properties of 1-Octyl-3-methylimidazolium Chloride 
Nicolas Goujon, Nolene Byrne, Tiffany R. Walsh and Maria Forsyth

We show the influence that two metal salts, zinc chloride and magnesium chloride, have on the transport properties of the nanostructured 1-methyl-3-octylimidazolium chloride, OMImCl, at varying water concentrations. The impact the metal salts have on the transport properties is directly related to their water structuring or destructing capabilities.

Synergistic Antibacterial Activity of Nanohybrid Materials ZnO–Ag and ZnO–Au: Synthesis, Characterization, and Comparative Analysis of Undoped and Doped ZnO Nanoparticles 
Adriana Berenice Pérez Jiménez, Carlos Alberto Huerta Aguilar, Jorge Manuel Vázquez Ramos and Pandiyan Thangarasu

Because ZnO and Ag nanoparticles (NPs) effectively inhibit foodborne pathogens, both metals are expected to produce a more effective inhibitor as a result of hybrid properties. It has been reported that Ag-doped ZnO NPs and ZnO NPs do not show much difference in antibacterial activities, but show an increase in bacterial inhibition. To explain why doping of Ag NPs, unlike Au NPs, in ZnO NPs influences the antibacterial activities, ZnO, ZnO–Ag, and ZnO–Au NPs were synthesized.

Probing Mechanisms of Aryl–Aryl Bond Cleavages under Flash Vacuum Pyrolysis Conditions 
Edward A. Jackson, Xiang Xue, Hee Yeon Cho and Lawrence T. Scott

Flash vacuum pyrolysis (FVP) of phenyl-substituted polycyclic aromatic hydrocarbons (PAHs) promotes the formation of new rings by thermal cyclodehydrogenation reactions; however, such reactions are often accompanied by competitive loss of the phenyl group. Such ‘phenyl loss’ reactions cleave strong aryl–aryl bonds and are therefore important to understand. As probes for the mechanism(s) involved in the ‘phenyl loss’ reaction, FVP experiments were conducted with several phenyl-substituted PAHs and larger biaryls.

NAY SAYers. Those wishing to utilise nonstabilised azomethine ylids have the right to complain about reaction condition choice. Higher temperature conditions predominate over lower temperature conditions, which limits the application of azomethine cycloadditions to robust dipolarophiles. We present a mechanistic analysis of the application of the Roussi reaction for low-temperature generation of nonstabilised azomethine ylids to the challenging substrate N-methylmorpholine N-oxide.

Indigo Dreaming 
Ian D. Rae

Ian Rae, Roger Brown’s first Ph.D. student, explored dithiole chemistry but failed to synthesise thiolutin. Now a historian of chemistry, he recounts the story of J. F. G. Fletcher, who returned to Australia in 1919 after munitions work in Britain, dreaming of the synthesis of indigo from naphthalene. He succeeded, but was unable to commercialise the process.

Carlos A. Murillo
pp. 972-979

An account is provided of how the destabilization of a delta bond in quadruple bonded species by bicyclic guanidinate ligands leads to record low ionization energies of thermally stable compounds and concomitant production of very strong reducing agents. This paper commemorates the 50th anniversary of the seminal paper published on September 18, 1964 in Science describing how interactions between d-orbitals lead to a quadruple bond in species with idealized D4h symmetry.
